Answer:
6 and 7
Step-by-step explanation:
10(13-X) + X= 13-9X. 3×2=6. 7-6=1. 7+6=13
At a race, there are 3 rows with 15 people in each row. How many total people are there?
Numerical expression- 15 times 3
(Idk if this helped very much but it's worth a shot)
If point A is the midpoint then that means line segments XA and AY are equivalent so you can set:
3x=5x-6
(now you solve for x)
2x=6
(divide by 2 on both sides)
x=3
So BASICALLY,
XA= 3x= 3(3) = 9
AY= 5x-6= 5(3)-6 =9
So now you know the length of both sides, add those together and you get
XY=18
<u>Answer with step-by-step explanation:</u>
We know that the formula for area of a circle is given by:
<em>Area of a circle =
</em>
So to find the area of circle, we basically need to know the radius of the circle.
If we know the circumference of the circle, we can calculate the area of the circle too.
Formula for the circumference of the circle is given by:

So if we know the circle's circumference, we can find the value of radius and then find the area of circle with it.
